Here, we report the structural features and mechanism of action of ZK2B10. The crystal structure at a resolution of 2.32 Å revealed that the epitope is located on the lateral ridge of DIII of the envelope glycoprotein. Cryo-EM structure with mature ZIKV showed that the antibody binds to DIIIs around the icosahedral 2-fold, 3-fold, and 5-fold axes, a distinct feature compared to those reported for DIII-specific antibodies. The binding of ZK2B10 to ZIKV has no detectable effect on viral attachment to target cells or on conformational changes of the E glycoprotein in the acidic environment, suggesting that ZK2B10 functions at steps between the formation of the fusion intermediate and membrane fusion. These results provide structural and mechanistic insights into how ZK2B10 mediates protection against ZIKV infection. 履歴 登録 2019年2月7日 登録サイト : PDBJ / 処理サイト : PDBJ改定 1.0 2019年5月15日 Provider : repository / タイプ : Initial release改定 1.1 2019年5月22日 Group : Data collection / Derived calculationsカテゴリ : pdbx_struct_assembly / pdbx_struct_assembly_gen / pdbx_struct_assembly_propItem : _pdbx_struct_assembly.details / _pdbx_struct_assembly_gen.asym_id_list / _pdbx_struct_assembly_prop.value
